Application filed March 17, 1926.

This invention relates to improvements in nursing bottles, particularly in the construction of the nipple.

It is well known that the ordinary nipple has a comparatively short life. They are subjected to frequent cleaning and should be made perfectly sanitary. Nipples in common use are applied to nursing bottles by directing the lower portions downward and stretching them over the outside of the bottle. This stretching distorts the nipple, which soon loses it useful qualities, and assumes a permanent set in the stretched con I dition thereby loosely fitting the nursing bottle and causing leakage. An object of this invention is to provide a nipple for a nursing bottle, which will be sanitary, easily and quickly applied to the bottle without stretching the nipple material, and practically proof against leakage.

A further object of this invention is to provide a sanitary nipple which may be readily applied to and removed from a nursing bottle and thoroughly cleaned without damage to the nipple.

This invention furthermore, provides an improved sealing means, thereby eliminating the common objectionable leakage between the bottle and the nipple.

Another object of this invention is to provide a one piece nipple consisting of a soft upper section and a hard lower section, the nipple being constructed in one piece and of the same material throughout, the hard lower portion being provided with a fastening means adapted to cooperate with a suit able fastening element on the bottle.

The upper and lower sections of the nipple in this invention, although having different characteristics of hardness and softness, are integrally joined together thereby forming a one piece nipple, the upper section having a soft and pliable characteristic, is adapted to be suitably reinforced or constructed in such a manner that the nipples will not materially collapse due to the creation of a partial Vacuum therein, a disadvantage which is of common occurrence.

Other-objects will appear in the following detailed description of the nursing bottle and nipple, and in the two sheets of drawings which are herewith made a part of this application.

Serial No. 95,409.

In the drawings,

Fig. 1 illustrates a side elevational view of a portion of the nursing bottle showing the nipple in attached relationship thereto.

Fig. 2 represents a vertical sectional View of the nipple.

Fig. 3 illustrates a vertical sectional view of a portion of the nursing bottle and nipple in interlocked relationshi Fig. 4 is a plan view taken on line 44 of Fig. 1.

Fig. 5 represents a sectional elevational view of a portion of the nipple, disclosing in this invention, a modified form of lug for bringing the nipple into interlocked relationship with the neck of the bottle.

Fig. 6 illustrates a sectional view of modified form according to this invention of the sealing means between the nipple and bottle.

Numeral 1 designates a nursing bottle made of any suitable material such as glass having an upper portion 2 adapted to be provided with lugs 3, which are adapted to be brought into interlocked relationship with cooperating lug portions 4 which are integrally formed in the lower section 5 of the nipple 6. The nipple 6 in this invention is preferably constructed or formed of the same general material throughout, the lower portion 5 having a hard characteristic, and the upper portion 7 being of a soft pliable nature.

The nipple 6 according to this invention is formed of a material suitable for nipples such as rubber. It is preferredin this invention to make the nipple of two separate pieces of material, the upper portion 7 being of a soft pliable nature, and the lower section 5 having a hard characteristic adapted to hold the lugs 4 of the nipple in firm interlocked relationship with the lugs 3 of the nursing bottle without losin its usefulness as an effective bottle closing element through repeated use. The uppersection and lower sections 7 and 5 of the nipple 6 are adapted to be integrally joined together at 22, by any suitable means such as the mold disclosed in Fig. 6, the upper and lower portions of the nipple are formed having interlocking edges 23 suitably formed for integrally connecting together in a mold orv otherwise. The interlocking edges may be formed in such a manner that a section 24 of the soft upper portion 7 of the nipple will contact with the u per edge surface 25 of the nursing bottle when the nipple 6 and bottle 1 are in interlocked relationship, hereby forming an eflicient sealing means between the nipple and' bottle, the soft portion 24 of the nipple being adapted to keep the liquid from seeping through between the nipple and bottle. It is to be understood, however, that this invention does not limit itself to the soft upper portion of the nipple as the sealing means. A portion 26 of the lower section 5 of the nipple may be, if desired, utilized as the contact portion between the nipple and bottle, and act as the sealing means.

Fig. 5 of the drawings represents a modi tied form of interlocking lug 27, which is adapted to be suitably fastened within the lower portion 5 of the nipple 6.

This invention provides a nipple for a nursing bottle, having effective means for sealing-between the bottle and nipple, thereby eliminating the objectionable leakage common to ordinary nursing bottles.

The nipple in this invention is formed having a soft upper portion and a hard lower portion upon which the lugs are formed for interlocking with the cooperating lugs on the bottle, thereby providing a closure element that will not weaken under repeated use.

It will be understood that various changes, substitutions and modifications may be resorted to without departing from the scope or spirit of this invention.

What I claim is:

1. In a nipple for a nursing bottle, comprising an upper portion of soft material, and a lower portion of hard material, the two portions being integrally joined together, engaging lugs extending inwardly of the lower portion, and sealing means between the bottle and the nipple, bringing the upper section of the lower portion into relationship with the lower section of the upper portion in such a manner that a section of the soft material will contact with the upper periphery of the bottle thereby forming an effective sealing means whenever the bottle and nipple are firmly connected together.

2. In a nipple for a nursing bottle, comprising an upper portion of soft material, and a lower portion of hard material, the two portions being integrally joined together, engaging lugs extending inwardly of the lower portion, and sealing means between the bottle and nipple bringing the upper section'of the lower portion into interlocked relationship with the lower section of the upper portion in such a manner that a section of the soft material will contact with the upper periphery of the bottle thereby forming an effective sealing means whenever the bottle and nipple are firmly connected together.

In testimony whereof I aflix my signature.
